PLEASE HELP DUE TMR 11 1. A 3 kg book at rest on a table top.

2. A 15 kg chandelier is hanging from the ceiling.

3. An 1.5 kg egg falls from a nest and accelerates toward the ground with an acceleration of 3 m/s2.

4. A 50 kg hang glider is gliding through the air towards the ground with an acceleration 5 m/s2. Include air resistance.

5. A rightward force of 15 kg is applied to a 2 kg book in order to move it across a desk with a rightward acceleration of 4 m/s2. Consider frictional forces. Ignore air resistance. A free body diagram for this situation looks like this.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
